SIGNAL.

Application led February 1, 1922. Serial No. 533,272.

T o all whom t my concern:

Be it known that I, CHARLES IV. BROWN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Signals, of which the following is a specification.

This invention relates to signals adapted for use on motor cars to indicate, at night as well as in the day, the direction in which the car is about to turn, and which may also be used to indicate that the car is about to stop or to start.

This invention consists in the novel construction and combination of the parts hereinafter fully described and claimed whereby two electric glow lamps are supported and are operated by hand to effect the required signals. i

In the drawings, Figure 1 is a front view of a signal constructed according to this invention. Fig. 2 is a sectional plan view, taken on the line 2-2 in Fig. 1. Fig.v3 is a cross-section, taken on the line 3 3 in Fig. 2.

A casing 6 is provided, and is secured to the motor car at any suitable point. The front 7 of the casing has two horizontal arrows 8 and 9, arranged one above the other and pointing in opposite directions. The front may also have other indicators, such as the words Left and Right, or may have both arrows and words. The interior of the box is coated with white enamel 4 to reflect the light, and the arrows are preferably formed of red glass 5 covering arrowshaped openings in the front 7. The casing is provided with horizontal guides 10 at its middle part between the arrows, and its front 7 is removable. The back lof the casing may also have arrows the same as its front. y

A plate 12 of insulating material is provided, and is slidable horizontally on the guides 10 which are preferably formed of metal together with the casing, and are grounded by any approved means. The plate 12 has two holes 14, and 15 and 16 are two electric lamps of approved construction supported by the plate 12. The lamp socketsl are slid into the holes 14C, and one lamp is arranged to project upwardly and the other downwardly so that the light from The lamps have end contacts 19 in the usual way, and 2O are contact springs which bear on the contacts 19, and are secured to the plate 12 by bolts 21. Line wires 24 and 25 are secured to the bolts 21, and project through a short tube 26 let into the bottom of the casing. The wires are provided with a suitable electric battery 27 and switches 28," so that a current of electricity may be sent through either lamp, or through both of them simultaneously.

The lamps can be renewed with great facility by sliding the plate 12 out of the casing after the front is opened. A sounder or annunciator of any approved construction may also be advantageously included in circuit with each lamp, to draw attention to the signal illuminated by it. The direction of each arrow corresponds with the direction the car is about to 'take in turning, and when both arrows are illuminated it indicates that the car is either about to stop or to start.

What I claim is:

1. In a signal, a casing provided with a front having direction indicators arranged one above another, said casing having also horizontal guides at its sides between the indicators, a plate of insulating material slidable on 'the said guides and provided with lamp holes, electric lamps having their sockets inserted in the said holes, means for grounding each lamp independently of the other` said lamps being arranged to project one above and the other below the said plate, andmeans for completing an electric circuit through each lamp to illuminate the indicator to which it pertains.

2. In a signal, a metallic casing provided with a front having direction indicators arranged one above another. said casing having also horizontal metallic guides at its sides between the indicators, a plate of in- Sulating material having its ends slidable ai i l 1,457,818

on the said guides, said' plate having lamp guides, and means for completing an elechole's in its middle portion and radial holes tric circuit through each lamp to illuminate extending horizontally between its lamp 'the indicator to which it pertains. 10

cal contact springs arranged in the radial holes between the lamp sockets and the said CHARLES W. BROWN.
